We would like to take the ferry from Zadar to Brbinj tomorrow at 10am with a carwe would like to know if we have to reserve or if we can take the tickets tomorrow before the travel?And other question, the price (176kn) for the car include the foot passenger or not?

its local ferry, first come first served, so yes, buy your ticket just before your travel in the port. that price is for car only, so additional fare apply for foot passenger
